ofpthe particular material of which it is made, is especiallywelladapted for use in building up the wheels of heavy road vehicles such astrucks or lorries; 7

Wheel fellies, asis generally known, 1 are ordinarily strips or thelike; but the practical utility of fellies of thattype isnecessarilyinfluenced, to some extentat least,by prevailing atmosphericand climatic conditions, this particularly true-of certain Eurobeingpean countries, especially England, where wooden felly wheels areseriouslyafiecfted by changes in temperature, dryness and m ois-' ture,and must be sent at frequent intervals tothe wheelwright for tighteningand resetting of their steel bands or rims.

It is the essential purpose of my 'inven- .tion to overcome this defector difficulty, by providing a telly as clistinct'froma tire thatis madeup of a basic material which is wholly unaffected .by' climatic andatmospheric changes and, in consequence, is not subject to expansion andcontraction therefrom,"'and which is of such a character as toconstantly tend tomaintain its original position or shape, with theresult that a felly, when constructed as hereinafter described, and :inplace on the finished wheel,

will impose an outward pressure radially against-the steel rim at allpoints thereof, thus holding the latter tight at all times byimmediately taking up any slack which may arise 'from'any cause. a I

Referring to the accompanying drawing: Figure 1 is a side elevation of alorry wheel equipped with the improved felly.

The block A is built up of layers of these strips a ofwoven coir yarn, laid one upon another as and 4, each layer alternatingwith a layer of rubber or other .vulcanizable gum 01' Some of the stripsa are woven. with the selvages at the side, and some with the selvagesat the end, and the strips may be so arranged that the selvages come tothe sides and ends of the blocks alternately; or,

if preferred, s0 that-the warp yarns of the successive layers runalternately longitudinally and transversely of the block, in which eventthe warp yarns of one layer will cross those of the next layer, resentedin Fig. 4. i It is also preferable, in one or to fold or lap overtheextended portionsa shown in Figs. 3'

as repp so as to impart a more finished appearance .tothe block ends.

Instead of utilizing woven coir fabric, the blocks may be built up in asimilar manner ofseparate strands, or hanks a of coir yarn (Fig. 5),laid alternately endwise and crosswise of the blocks; and in place ofthesirr gle woven strips or layers of fabric, a number of layers of thefabric may be woven together in amanner similar tothat followed 40 r ythe metal rimor band C, which latter may in the manufacture of what isknown as manner, with the that the component blocks or segments ofare sosolid woven belting, where several plies are Woven together in a loom.In any case, however, the strands, strips or layers of coir are boundtogether by the rubber or other 'vulcanizable material, which ispreferably laid between each layer or strand in the'torm of a thin'sheetor granulated layer.

The blocks,

dies under great pressure, tion, heat being applied at the same time, soas to effect the vulcanization of the rubber and thereby; form ahomogeneous mass. Each block is constructed and compressed separately.When compressed and finished, the blocks ar'e bored at a (Fig. 6) totake the ends of the spokes B though they may, if desired, be moldedwith these spoke seats. Thereafter, the parts ofj'the wheel areassembled in a wheel press, in theusual blocks encircled by the metalrim C, and the inner ends of the spokes secured in sockets d in the hubDby a hub late d, (Figs, 1 and 2). The blocks bjected to further pressurewhile in the wheel press, as will be understood, the pressure appliedpreferably being even greater than that imposedupon them during molding.Consequently, the fibers of the blocks are ultimately compressed to thelimit of their compressibility, so that no further compressionthereotcan be effected by the working load u on the wheel. 7

The finished wheel as the great advantage over the ordinary wooden tellywheel the fel'lyhave the constant tendency to move radially outward, or,in other words, con stantly exert an outward pressure against eitherconstitute the tire of the Wheel or may serve merely as a carrier forresilient or pneumatic tire.

Furthermore, the improved tel y is extremely durable,owing to the natural toughness of thefcoir;
